Control III Disinfectant Dilution

This concentrate is some nasty stuff.  Please read and understand the dangers of handling this liquid and take precautions as needed.  The specifications can be found here and FAQs can be found here.  That being said, if diluted properly, this is a strong disinfectant and can be used when other easier solutions are not available.



The diluted solution works through prolonged contact - basically spray it on and let it sit for 10 minutes, or soak something in a bucket.  Note that once you mix a batch, it is only good for 2 weeks before it needs to be disposed.  A 32 oz (946mL) bottle such as below is a good option.



Two snippets of the label directions are below: 

 


Depending on what you are doing, make a dilution that is up to 1 oz (29.5735mL) per 1 gallon (128oz) of water.

If you are measuring in metric, a little math is needed to get the proper amount for a 32 oz spray bottle:
= mL per ounce * ounces per container / mL per gallon
= 29.5735 * 946 / 3785.41
when you do the math without rounding, you get
= 7.39338 mL per 32 ounce spray bottle

Since I'm not operating in a hospital, I generally round down and use 3.5mL to 7mL per 32oz spray bottle, measured in a graduated cylinder...

Root 3 CNC - Preparing the Control Cable

The following cable is being used for the control cable:

Control cable Lapp ÖLFLEX 190 CY 4G1.5 16/4C (4x1.5/16 AWG) - 601604CY

In order to ready the wire for use, both ends must be prepared.  To prepare the GX16 end, the outer jacket and braid were removed:

then the conductors were soldered (dont forget to slide on heat shrink tubing before soldering):

A test fit shows that the connector fits well:

To complete the other end, first the outer jacket was removed, and the braid unwound.  A few bundles of braid were weaved together to form a wire:

If you have big hands, these tools are fantastic for getting into tight places like the braid disassembly:

A segment of the 16awg ground wire was soldered onto the braid:

and then covered in heat shrink tubing:

Finally the braid cable was marked with white electrical tape, and the end covered in heat shrink tubing:

The completed cable:

Root 3 CNC - Programming the HY02D211B VFD

Before connecting the spindle, the VFD has an initialization process to configure the device's firmware.  This apparently varies greatly per VFD, and in all instances seems to be documented poorly, so do your research and hope for the best.

The VFD/spindle bundle I purchased was from Amazon.  It contained a 110V VFD which upconverts to run a spindle at 220V (at least, I'm fairly sure thats what I bought).  The specific VFD model can be seen below (HY02D211B):

There was a video posted to Amazon which documented the settings required for this VFD as well as the process for programming:

• PD013 = 8 (factory reset)
• PD005 = 400 (max operating frequency)
• PD004 = 400 (base operating frequency)
• PD002 = 1 (set potentiometer control)
• PD070 = 1 (set analog input)
• PD072 = 400 (set high analog frequency)

This alternate video also describes the programming process well, but for a different model VFD (so the parameters do not match exactly).

In order to program the device, you must first connect the VFD to power without wiring the spindle (not sure the spindle not being there really matters, but I tried to follow the video steps).  This presented the first hurdle, as a complete wiring diagram was not included in the manual.  A little online research and a lucky guess provided the solution.  First remove the wiring access panels on the VFD:

Then run a 12/3 wire (in this case, 12/3 SJOOW) and connect as follows:

• Black (HOT) to R
• Neutral to T
• Ground to Ground

After reassembly and powering on the device, the programming can be completed using the following steps:

• PRGM (to start the programming sequence)

Then for each parameter, perform these steps:

• Up/Down arrows to select PD00x parameter
• SET
• Up/Down arrows to select value, SHIFT can be used to move the cursor
• SET (to accept the value)

Finally, to complete the programming, press:

• STOP (big red button to complete the programming sequence)

After completing this process, the next step is wiring the spindle to the VFD, to be covered in a future post...
